STEAM CONFECTION-PAN.

SPECIFICATION forming part of Letters Patent No. 391,368| dated October 16, 1888.

Application filed March 8. 1887. Serial No. 230.077, (No model.)

.To all whom it may concern:

Be it known that l, VILLIAM L. JANcEY, of Chicago, county of Cook, and State of I1linois, have invented certain new and useful Improvements in a Steam Confection-Pan, of which the following is a full, clear, and exact description, that will enable others to make and use the same, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to improvements in that class of machines used in the manufacture of certain kinds of confection wherein the same is required to be rolled and dried by the application of steam-heat during thev rolling process.

The object of this invention is to so construct a machine of this character that the joints and connections may be conveniently kept steam and water tight in order to prevent the escape of either one.

Figure l is a side elevation of a machine embodying my improved features; Fig. 2, a longitudinal plan section; Fig. 3, a broken-away sectional detail; and Fig. 4, a transverse scction in the plane 4, Fig. 2. Fig. 5 is a brokenaway side elevation showing the confectionpan in place and the steam-heating coil encircling the same.

In the drawings, A represents the pedestal or supportingframe; A', the cross on which the confection-pan A'l is mounted; A3, the stea mcoil encircling said pan; and B, the hollow shaft, to which the cross and pan are rigidly secured. The shaft B is usually set at about the angle shown, and rotates in the journal-boxes a a', the lower halves of which are formed on the pedestal, the upper halves or caps being removable.

B is a bevel gear-wheel rigidly mounted on the hollow tapering shaft B. This gear-wheel engages with the corresponding: pinion, B2, mounted on the shaft C, set at right angles to the hollow shaft. The shaft C is provided with suitable journal-bearings on the enlarged cap part of the supportingpedestal, and has the band-pulleys mounted on the outer end thereof, which receive the belt running from the motive power. By the arrangement described the required rotary motion is transmitted to the hollow shaft.

The front or largerend of thehollow ortubular shaft B is closed, the steam-supply pipe C running longitudinally through the chamber a2 therein and terminating near the closed end, as shown in Figs. 2 and 3. At this point the steam-pipe C screws into the inner projecting end of the hollow tapering plug a tapped into the shaft B and entering at right angles to the steam-supply pipe. rlhe opening in the mouth or outer end of the hollow plug a3 is somewhat enlarged and gradually contracts inwardly to the uniform passage a4, as shown in Fig. 3. The tapering end of the pipe a5 is inserted in the enlarged opening in the plug a3, and is drawn into a close union with the v same by means of the screw-cap b, which has a threaded engagement with the outer exterior end of the hollow plug a3, and bears against the annular shoulder b', formed on the pipe a5, which is the starting-point of the system or coil of steam-pipes encircling and heating the confection-pan. The exhaust-plug b2 and eX4 haust end b3 of the system of heating-pipes are connected in the same manner as that already described for the supply side. The exhaust discharges into the chamber a2 in the hollow shaft B, and is finally conducted oil1 through the valve b4 inserted in the hollow shaft near the back end. By this means the steam supply and exhaust connection are made abso lutely steam-tight, thereby dispensing with the use of the different kinds of packing commonly employed and with which it is impossible to keep the joints tight, in view of the peculiar operation of the machine.

D is a double stuffing box,the part d of which is made to closely fit around the back end of the hollow shaft B, thus providing alarge bearing for the stuffing-box, and serving to keep the same in line with the hollow shaft. This .stuffing-box is longitudinally adjustable on the IOO is kept away from contact with the end of the same, and cannot be blown out, as was the case under the old arrangement. This form of stuffing-box also keeps in perfect line with the hollow shaft, and is therefore also less liable to leak.

The smaller end of the stuffing-box D is provided with the packingchaniber e, through which the steam-pipe C passes, the open end of which enters the passage e in the packinggland e2, as also does the end of the pipe E, which conducts the live steam from the generator. The bolts c3 e4 adj ustably connect the packing-gland e2 with the smaller packing end of the double stuffing-box D. This form of a 'stuffing-box makes it possible to keep the parts to which it is applied perfectlyt-ight with the expenditure of but little time and labor, the

packing requiring to be renewed only at long intervals. The gear-wheel mounted on the hollow shaft is also moved forward nearer to the front end, and the front leg, F, of the supporti-ngpedestal curved outwardly, so as to bring the same farther under the heavier part of the machine, in order to better balance the working parts and steady the same against undue vibration, which has a tendency to affect the steam-joints and cause the same to leak.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is-

The combination, with a confection-pan, of the hollow shaft B, the steamsupply pipe C', the steam-coil A3, encircling said pan, the hollow plug a3, having a tapering passage contracting inwardly and inserted in said hollow shaft and connecting the steam-pipe C and the heatingcoil A3, the screw-cap b,and the hollow exhaust-plug b, inserted in the hollow shaft at a point opposite to the plug a3, whereby steamtight connections are formed between the parts described without the use of packing, substantially as and for the purpose set forth.
